San Francisco-based ThinkSmart is Mitratech’s eighth deal and will serve as its West Coast hub.

Austin-based legal software maker Mitratech, which has grown through acquisitions, has done another deal.

The company said it has purchased San Francisco-based ThinkSmart, which sells workflow automation software for handling legal work.

ThinkSmart’s San Francisco offices will serve as Mitratech’s West Coast hub, the company said.

Mitratech’s software is used by legal departments which use it to handle managing records, tracking documents, electronic billing and compliance.

The company has more than 1,200 corporate customers in more than 160 countries. They include Chevron, Xerox and Buc-ee’s.

Mitratech was founded in 1987 Los Angeles and opened an office in Austin in 2012 to tap into the area’s talent base and tech community.

The company has since moved its headquarters to Austin and has 300 employees, most of them based here.

ThinkSmart, which was founded in 2014 and has 20 employees, is the Mitratech’s eighth acquisition.

ThinkSmart’s platform was designed to accelerate legal operations by replacing paper-based workflows with automated processes, which is says reduces errors and cuts cost.

“Individually, each company has been a factor of change in the industry,” said Mitratech CEO Jason Parkman. “Combined, we’re positioned to open up the ‘next frontier’ for legal operations.”

Mitratech was previously backed by Austin’s Vista Equity Partners, and was then acquired by TA Associates Management, a Boston private equity firm. It is now owned by Equity Partners HG, a private equity firm based in Easton, MD.
